SPECIFICATION formingpart of Letters Patent No. 664,558, dated December 25, 1900. Application led February 2, 1900. Serial No. 3,675.v (No model.)

. is a specification, like letters on the drawings representing like parts.

My invention is an' improved lockrod for card indexes, records, duc., having for its ob,- ject the provision of asimple and inexpensive device of the eXpansible lock-rod kind capable of instant operation and provided with means for not only locking the cards, but for locking the device itself against accidental operation.

In carrying out my invention I preferably employ wires or other suitable forms of inexpensive lock-rods, said rods being pivotally mounted at their opposite ends in the holder or card-receptacle and provided, preferably, at one end with actuators, whereby upon the rocking or turning of one lock-rod the other is simultaneously and similarly operated, and in connection with one or both of these locking members I provide an automatic stop or lock proper.

It will be understood that various details of my invention, as more particularly described hereinafter, are novel in and of themselves, and accordingly I do not intend to restrict myself in all respects to thel construction as herein shown, nor otherwise than as expressed in the claims.

In the drawings, in which I have shown a preferred embodiment of my invention, Figure l is a' perspective view of a card-holder of suitable or typical style in which my cardretaining device is mounted, parts being broken away for convenience of illustration. Fig. 2 is a top plan view thereof. Fig. 3 is al1-enlarged detail showing my invention in top plan, the end portions of the holder being in section. Fig. 4 is a transverse vertical section on the line 4 4, Fig. 3. Fig. 5 is a View Similar to Fig. 4, showing a card in locked position and indicating the unlocked position of the parts in dotted lines.

My invention is applicable to any suitable in card-holders.

holder or receptacle, a tray a of usual'kind being herein indicated for convenience.

The holding device as herein shown cornprises two members a a2, mounted in any suitable Way at the rear end of the box, as by being pivoted at a3 in a suitable plate a4, and at their opposite ends said rods are provided with interlocking devices, herein shown in the yform of small pinions a5 0,6, said pinions being suitably journaled in the box or an adjacent part, being herein shown as housed between the front a7 of the box and a usual inclined block a8, such as is ordinarily found The rods or locking members a a2 are secured to the pinions a5 a eccentrically in order that they may be rocked in parallelism therewith relatively to the axes of said pinions the same as they are relatively to their opposite pivots a3. One ofsaid pinions, herein shown as the pinion a5, is provided with a projecting stem a9, extending out through the frontof the receptacle and provided with a suitable knob 0.10 or other device to be grasped by the operator in operating the locking members. Apin impasses through this stem and is adapted to fit in a slot 0,13, provided in an escutcheon' 1.14, fixed on the front of the box, and said stem carries a spring a15, bearing at one end against the inside of said escutcheon and at the other end against the pinion a5, thereby tending to retain said pin @12 in said slot @13. This construction is one means of automatically locking the holding members against accidental rotation, inasmuch as they cannot be rotated while the pin w12 is in the slot 0,13. In order to operate the members a a?, the operator grasps the knob a1 and pulls on the same against the spring 0.15, so as to remove the pin @12 from its full-line position, Fig. 3, to its dotted-line position, whereupon the knob d10 and pinions a5 a6 may be rotated, thereby correspondingly rocking the locking members a a2. I have shown the parts in unlocked position in Fig. 2 and in locked position in Fig. 3. When the stem a9 is pulled outwardly, the pinion a5 slides slightly on the pinion a6, said pinions having sufficient depth t-o permit of this movement.

In the bottom of the box I provide arecess or chamber d. in order that the members a. a2 when in operativeposition maybe depressed into saidrecess into the position shown in full lines in Fig. 4 and in dotted lines in Fig. 5, thereby being removed entirely from any possible contact or interference With the cards in the box. This feature is of considerable importance, inasmuch as the cards (L17, being cnt substantially as shown in Fig. 5, are very liable to have their projecting ends als torn 0E or mutilated by contact with the retaining device. i

It will be obvious that when the rods a a2 are in their lowermost position, housed within the depression or recess 0.16, itis impossible vfor them to interfere in any way with the cards.

In use the operator pulls out on the knob am, thereby withdrawing the pin (L12 from, its recess ctfand he then gives the knob a halfturn over to the right, Fig. 1, thereby bringing the parts into the position shown in full lines, Fig. 4, in which position the pin 0.12 will snap back int-o the slot al?, locking the members alo? in their lower-most position. A reversal of this movement raises the retaining members a' a? into their uppermost or card-v locking position.

It will be understood that I do not limit myself in all respects to the details herein shown.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1.. A card-holder, having a card-retaining device mounted therein,comprising two members capable of swinging in the arc of a circle, intermeshingpinions connecting said twomembers, and means for locking said pinions against rotation.

2. A card-holder, having a card-retaining device mounted therein,comprising two members capable of swinging in the arc of a circle, intermeshin g pinionsco-n necting said two members, one of said pinions having a stem extending through the holder and movable having a movable locking member, and means to move said member, including a rotary stem projecting through the' front of the holder, said stem being movable longitudinally in said holder, and cooperating interlocking portions on said stem and said holder, said stem being maintained non-rotatable by' said interlocking portions when in its innermost position. y

4. In a cardfholder, a Gard-retaining device having a movable locking member,and means to Inovesaid member, including a rotary stem projecting through the front of the holder, said stem being movable longitudinally in said holden-,cooperating interlocking portions on Said stem and said holder, and a spring normally holding said rotary stem inwardly, pressing toward the rear end vof the holder maintaining said interlocking portions in engage-ment and the stern looked against rotation.

5. A card-holder, a card -looking device mounted therein, and eomprisinga plurality of locking members secured at their opposite ends in said holder, a recess or chamber extending longitudinally of said holder in the bottom thereof beneath said card-locking device, and operating means for `moving said locking members `into said chamber out of contact with the cards for releasing the latter and up out of said chamber into contact with the cards for locking the said cards.

In Vtestimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
